.SPECIFIGATION forming part of Letters Patent No. 537,417, dated April9, 1895.

` i Application led May 31,1893. Serial No. 476,074. (No model.)

-JZ'o all whom it may concern.-

Be it known that I, OswALD HEINRICH, a subject of the Emperor ofGermany, residing at Mittelwalde, in the Province of Silesia,

5 Germany, have invented certain new and useful Hinged-Joint Links forJoining Walls of Boxes or Oasings, of which the following is aspecification.

This invention relates to a hinged joint-linkV xo for joining walls ofboxes and casings and the object of this improved joint-link is toafford the possibility for joining walls of boxes and casings in anyposition to each other.

Each joint-link consists of two plates catch- 15 ing into each otherwith sockets and held in position by means of a pin passed through thesaid sockets. The other edges of the plates are fastened to the edges ofthe walls to be joined.

In the accompanying drawings: Figures 1,

ln and lb show one form of my improved fastening. Figs. 2 and 2, 3 and 3and t and 4fl show modiiied forms of the means for fastening the jointto the box. z 5 In Figs. l, la and lb one form of my hinge connection isshown consisting of eyes or sockets a with intervening spaces adapted toreceive like eyes, the connection between the two being made by a rodupon which the eyes pivot.

My invention relates particularly `to the manner of securing the eyesections to the box or case.

.As shown in Fig. l, the eyes or sockets are 3 5 formed on the edge ofthe plate a, of metal and the plate is secured to the box c, as shown inFig. 1b, by bending back upon itself the lower part of the plate aclamping the material of the box or case which is exible between theparallel surfaces.

As shown in Fig l instead of forming the eyes on the edge of the platethey may proj ect from the surface.

In Figs. 2 and 2a the lower edge of the plate is doubled back with theedge of the case or 45 box between the opposing surfaces, and the end ofthe doubled part together with the projection forces the material of thecase into recesses as shown in Fig. 2f.

In Figs. 3 and 3, the plate is provided with 5o a turned up lower edgehaving a series of projections like saw teeth and the doubled edge ofthe box or case engages with these proj ections.

In Figs. 4C and 4 the lower edge of the plate 55y a and the upper edgeof the case are rolled together as shown in Fig. 43.

In combination with the edge of a box or case, a joint plate having itslower end folded between the doubled upper end of the box or case and aseries of eyes on its upper edge, substantially as described.

Signed at Breslau, Province of Silesia, Empire of Germany, this 19th dayof April, 1893. 65-
